T0 all whom t may concern:

Be it known that I, REN CAUDRON, manufacturer, citizen of theFrench.Republic, residing at Issy-les-Moulineaux, Department of Seine,France, have invented certain new and useful Improvements inArrangements of Flexible Members; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to the arrangement of exible members, such aswires, cables or the like for use in controlling mechanism or for thetransmission of movement and it has for its object to improve thefunction of the mechanism in whlch such members are chiefly employed.

To this end provision is made according to this invention at the pointor points' where a wire, cable or the like used for controlling purposesor for transmission is .to operate with a turn or over a bend, in

addition to a rigid ide tube of a flexible rollen chain prefera ly inthe phase of or combined with the portion or portions of thetransmission wire, cable or the like which are to lbe guided in theinterior -of the guide tube as will be clearly understood from thedescription of the annexed drawing showing one' form of the invention bywa of example.

rranged as usual at the place where the transmission wire or cable istobe iven a turn or operate over a bend, is a rigi guide tube a of therequisite shape. The wire or cable, however, instead of passing throughthe guide tube a, freely as hitherto, is rovided with or at thisportion, replaced y a link chain b, with rollers of a diameter such thatthe chain cannot come into contact with the internal wallsV of the tube,except by means'of the said rollers.

. Attached, as shown," to thev extremities of v Specication of LettersPatent.

Patented Aug. 24, 1920.

1919. Serial No. 293,780.

A n .arrangement of this kind is useful in all cases where transmissionof movement is desirable over a turn or angularly, provided there is nochange in the actual plane of the bend. It may, with advantage, beemployed 1n the pull controls of flying machines or 1n the place ofother arrangements hitherto used for similar purposes.

What I claim and desire to secure by Letters Patent is 1. In a flexiblemotion transmitting mechanism the combination of a rigid curved tube, alink chain passing through said tube for joining two sections of aflexible control member, and rollers mounted on the link pins of saidchain and protruding `beyond the sides of the chain'so as to prevent thelinks of the chain from coming into frictional contact with said tube.

2. In ailexible motion transmitting mechanism the combination of a rigidcurved tube having its axis located in asingle plane, a flexibleoperating member having spaced controlling and -controlled sections, alink chain interposed between said sections and passing through said'tube, and rollers mounted on sald links ada ted. to contact with4 saidtube so as to su stitute rolling friction for the sliding friction ofsaid links. In testimony whereof I have hereunto set my hand in presenceof a witness.
